Overview
On EKG, endocarditis may be characterized by conduction abnormalities, low QRS voltage, ST elevation, heart block, ventricular tachycardia, and supraventricular tachycardia.[1]
Electrocardiogram
EKG may be useful in the detection of the 10% of patients who develop a conduction delay during infective endocarditis by documenting an increased PR interval. On EKG, endocarditis may be characterized by:[1]
- Conduction abnormalities
- Low QRS voltage, ST elevation
- Heart block
- Ventricular tachycardia
- Supraventricular tachycardia
